Don, Get a factory front sprocket if you're keeping the same 17 teeth. There were some spacing issues with aftermarket front sprockets I recall. A DID 530 ZVM chain is a good choice (that's what I used last time). Nowadays, I just drop 1/5 qt gear lube in the rear end at each oil change and call it a day :) -- Best regards, Julian mailto:jsolo at solo-tek.com
